Try this
In[1]:= Series[1/(1+x), {x,0,3}]
2 3 4
Out[1]= 1 - x + x - x + O[x]
In[2]:= Normal[%]
2 3
Out[2]= 1 - x + x - x
Cheers, Vittorio

I guess this should be simple and hiding somewhere in the manual. Is
there a quick way to remove the high order terms after using
Series[f,{x,x0,n}] command? The problem comes from the output is
actually given by:
expansion term + O(x^3);
the O(x^3) should be removed. I will keep trying but wondering if
anyone has a quick answer.
Thanks.
